Complies with BS EN 62208 and BS 7671 (18th Edition)
High immunity RCDs are engineered to ignore transient disturbances and harmonics that cause false trips in standard devices
Installer Tip: Choose the 63A MCB variant for high-load three-phase installs — such as industrial plant rooms or multi-charger EV hubs — where the standard 40A option may not provide enough headroom
It’s suitable for both domestic and commercial distribution boards where high-current three-phase protection is essential
and small sub-distribution panels across commercial three-phase boards
